1)Students will be able to explain how atoms interact. (p. 28-30)
a) The atom is composed of protons, electrons and neutrons. (Click Here For Video!)
b) A covalent bond shares electrons. (Click Here For Video!) (Click Here For Video!)
c) An ionic bond steals electrons. (Click Here For Video!) (Click Here For Video!)
d) A hydrogen bond is a weak bond with an unequal share of electrons. (Click Here For Video!)
e) An element is a pure substance whereas a compound combines multiple types of elements. (Click Here For Video!) (Click Here For Video!) 2)Students will be able to describe the different properties of water. (p. 31) (Click Here For Video!)
a) Cohesion allows water to form rain drops. (Click Here For Video!) (Click Here For Video!)
b) Adhesion allows water to stick to other surfaces. (Click Here For Video!)
c) Water absorbs heat slowly but retains it longer than other substances. (Click Here For Video!) 3)Students will be able to describe how water dissolves substances. (p.32-33)
a) A solution is created when one substance is evenly distributed within another.
b) The pH scale measures the strength of acids and bases. (Click Here For Video!)
c) An acid creates more hydrogen ions when added to water.
d) A base creates more hydroxide ions when added to water. 4)Students will be able to summarize the characteristics of organic compounds. (p. 34-37)
a) The four organic compounds include carbohydrates, proteins, lipids, and nucleic acids. (Click Here For Video !)
b) Carbohydrates are broken down into monosaccharides, which are used as a source of energy. (Click Here For Video!)
c) Proteins are broken down into amino acids, which are used for building muscles and protection against diseases. (Click Here For Video!)
d) Lipids are broken down into fatty acids, which are used for building cell membranes and storage of energy. (Click Here For Video!)
e) Nucleic acids are broken down into nucleotides, which are used for holding hereditary information or making proteins. (Click Here For Video!) 5)Students will be able to explain the importance of ATP. (p.37-42) (Click Here For Video!)
a) Chemical reactions absorb or release energy.
b) Energy is released from food and stored in the form of ATP for cells to use.
c) Enzymes help speed up chemical reactions. (Click Here For Video!) (Click Here For Video!)
d) How pH & temperatures affect enzyme activity. 6)Students will be able to connect the chemistry to the living world. (p.345-354)
